--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
for me, -O1 takes a long time even:
callgraph ipa passes : 2.34 ( 26%) 0.49 ( 30%) 2.84 ( 26%)
159M ( 37%)
-O2 is much worse:
alias stmt walking : 23.12 ( 37%) 0.14 ( 7%) 23.24 ( 36%)
323M ( 17%)
tree DSE : 11.34 ( 18%) 0.00 ( 0%) 11.36 ( 18%)
15k ( 0%)
tree slp vectorization : 16.01 ( 26%) 0.30 ( 15%) 16.32 ( 25%)
1117M ( 60%)
This is with --enable-checking=yes but with -fno-checking.
So there is at least a compile time hog here.
